IPC: H04B10/60
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To avoid an excessive stress on an LD by generating an abnormality alarm and switching automatic output light power control operation due to an APC to preset fixed light power output operation when the bias current of a transmission light source is excessively increased. SOLUTION: When the input voltage of a comparator 52 of a switching setting part 5 gets higher than a predetermined setting value 51, the output is turned to an L level and the cathode voltage of an RC: 53 is turned to a value determined by +Vcc and R. The base voltage of a transistor 32 of a driving part 3 is limited by the cathode voltage of the RC 53 and the base voltage is held at a fixed value. Thus, when a current exceeds the bias current set to a value just before the destruction of a semiconductor laser 11, a voltage to automatically control the driving part 3 from an APC part 2 is turned into fixed voltage and operation is switched to fixed bias operation. A light output detecting part 6 receives discharged light on the rear end face of the semiconductor laser 11 of a light emitting part 1 through a PD: 21 for monitoring and generates the output light abnormality alarm.
